1、TV broadcast bodywork design requirementsIntroduce bodywork design Install broadcast is a comprehensive system engineering, the body is the complex system is an important part of. In the broadcast, the body part in carrying out all broadcast video recording needed, audio and peripheral equipment, pr
2、ovide an outside the workplace. Not only such, still must ensure the safety equipmentoperation and smooth transhipment, The design quality, not only directly affect the task of broadcast programs, but also to the whole system of safe transport equipment.Bodywork design, is the first consideration in
3、 the broadcast of the design, the first thing to do, It will have a direct relationship to other system design.Bodywork designing technical requirements for design, should according to the hull of broadcast equipment size and purpose to choose, The general is installed cameras number, the risk is bi
4、gger also. According to the former chapter 8, use the broadcast cameras, can consider to choose medium broadcast. In television broadcast often faced severe external environment, and considering carrying equipment and broadcast task too many factors such as particularity, broadcast in the modificati
5、on of car when the car to the body, structure and so on a series of chassis project careful overall consideration, through special design and processing, can meet the basic requirements of television. The following are the technical requirements for design body.The safety performance of the broadcas
6、t must conform to the state auto industry standards, car body processing and chassis USES the overseas broadcast depot exterior processing technology, size and payload must conform to the state department of traffic regulations. Car chassis and selection: international famous brand high-end products
7、, the truck chassis on all equipment shall be loaded under the condition of the truck with 20% less than 200 surplus, engine, air suspension design, power electronic speed, hydraulic control 85KM/h, air conditioning system design, driving with anti-lock brakes (ABS) emission standards, with European
8、 standards, 111 2.5 meters wide.Car body requirements: TiZong compartments 10-11 meters long, no more than is 3.8 meters high and wide 2.5 meters, the right side is four meters long pull box. Box body use fixed number of year more than 15 years, the car body structure of aluminum alloy frame, with h
9、igh strength and insulation, Material requirement is accord with international standard of environmental protection, flame retardant materials. Vehicle requirements, dustproof, waterproof and sealed anti-rust, anticorrosion, preventing electromagnetic interference, antistatic, After the integration
10、of box body must be rain experiment (including the side after pulling open box, when jose) experiments, the static pressure side tilt impact experiment. The surface with high strength and durable products in the process of paint, paint baking room. Body after processing, vehicle has left from the An
11、gle, finally, from the smallest drive vehicle spacing, minimum turning radius basic technical parameters.Body: the space layout design requirements, and fully consider the reasonable layout of the camera, lens, earphone, tripod, cable, microphone, tools and equipment accessories storage space. For t
12、he car fixed equipment should consider appropriate carry scheme.In the national standard of vehicles, within the scope of the space as far as possible, spacious internal headroom maximization, the lateral pull section 2.2 meters, internal clear part and internal headroom wife 2.0 cars, cars GaoCheng
13、 4 meters in vitro.According to the different type of programme production division, scientific and reasonable utilization of working space. The workspace shouldHave partition, and pass the adornment with door, audio broadcasting acoustic requirements.Car chassis and selectionGenerally speaking, the
14、 car chassis and is generally together of choose and buy, the first to calculate the weight, then the broadcast and calculate the maximum weight, total quality, Choose total capacity calculation model is bigger than that.This design calculation, for example (hereinafter data for each half xiang esti
15、mated) :The total weight of two car electronic equipment nominal total weight (1 ton) + internal cables and connectors total weight (0.3 tons) ten outsideCable and cable reels total weight (0.5 tons of air-conditioning equipment and power) and total weight (l) + containing side and tons of heavy tru
16、nk TiZong compartments (5 tons) + car chassis total weight (5.5 tons) = 13.8 tons. Maximum loading 17.25 tons.Additionally, want to consider the traffic situation and task destination of local geography environment, For been poor road conditions or the environment, should choose the output power of the engine and have left corner to corner and Outlines the chassis (in after modification, this part of the parameters change), In order to protect the precision bearing,
